ISTR that I've read about some bugs with packet traversal through VM NAT 
It was something about the RST packet triggering NAT destruction but not 
being relayed further all the time (some race condition?!), that sounds 
as if it fit the bill here. comes close but 
is a bit old...

You could try to use the TCP keepalive settings in SSH, and/or to reduce 
the MTU size (as mentioned in another mail here already).

Else a few more setup details might help...
